carla leaderboard error:Boost.Python.ArgumentError: Python argument types in WorldSettings.__init__(WorldSettings) did not match C++ signature

Question

I'm learning the tutorial on https://leaderboard.carla.org/get_started/#11-download-the-carla-leaderboard-package%22, but when I run ./test_run.sh, the error occurred.

Trt
Traceback (most recent call last):

Boost.Python.ArgumentError: Python argument types in

did not match C++ signature:

My system version is Ubuntu 20.04, and the python version is 3.7.All the packages are downloaded by steps, I want to know how I can fix the error, and the the sample code. Thanks so much!

Answer 1

I had this error too when I was using variables to populate the WeatherParameters, e.g.:

cloudiness = 100
precipitation = 100
weather = WeatherParameters(
    cloudiness = cloudiness,  # range from 0 to 100
    precipitation = precipitation,  # range from 0 to 100
    sun_altitude_angle= 90 # degrees, 90 is midday, -90 is midnight
)

When I hard-coded the values, the error went away for me:

    weather = WeatherParameters(
    cloudiness = 100,  
    precipitation = 100, 
    sun_altitude_angle= 90 
)
